"There was an exemption for children over 65 pounds or 4' 9". Now they've dropped the pounds so it's just 4' 9", but it's much safer for a child to be in a booster seat than just a regular seat belt," says Tracey Weaver, with the Community Rescue Service in Hagerstown.
A child restraint is either a car or booster seat, or another federally approved harness.
